Children’s transitions in early childhood education and care : various combinations of dis-/continuities

2023

This longitudinal multiple case study explores children’s transitions within early childhood education and care (ECEC) in Finland. In ECEC children typically transition from one group or center to another. This study explores how physical, social and philosophical discontinuities and continuities constitute these transitions. Five focus children’s transitions were followed in and between separate ECEC centers. The data include interviews with parents and educators as well as observations noted. Fabian’s discontinuity division, which argues that transition consists of physical, social, and philosophical discontinuities, was used for content analysis of interviews as primary data. Interpretat…

Estimates for the Differences of Certain Positive Linear Operators

2020

The present paper deals with estimates for differences of certain positive linear operators defined on bounded or unbounded intervals. Our approach involves Baskakov type operators, the kth order Kantorovich modification of the Baskakov operators, the discrete operators associated with Baskakov operators, Meyer&ndash

Stability of Embankments Resting on Foundation Soils with A Weak Layer

2021

The presence of weak layers in geotechnical systems, including soil or rock masses, both natural and man-made, is more frequent than is normally believed. Weak layers can affect both failure mechanisms, in drained and in undrained conditions, as well as in static and seismic conditions, and the safety factor. In the present study, conducted numerically using the finite-element method (FEM) Plaxis 2D code, the influence of a horizontal thin weak layer on stress and strain distribution, on failure mechanisms and on the overall stability of an embankment was evaluated. The results obtained prove that when the weak layer is located at a significant depth from the foundation plane, the failure m…

The FLO Diffusive 1D-2D Model for Simulation of River Flooding

2016

An integrated 1D-2D model for the solution of the diffusive approximation of the shallow water equations, named FLO, is proposed in the present paper. Governing equations are solved using the MArching in Space and Time (MAST) approach. The 2D floodplain domain is discretized using a triangular mesh, and standard river sections are used for modeling 1D flow inside the section width occurring with low or standard discharges. 1D elements, inside the 1D domain, are quadrilaterals bounded by the trace of two consecutive sections and by the sides connecting their extreme points. The water level is assumed to vary linearly inside each quadrilateral along the flow direction, but to remain constant …

Il consumo del sacro. Feste lunghe di Sardegna quarant’anni dopo

2014

Quando nel 1971 Clara Gallini pubblica Il consumo del sacro. Feste lunghe di Sardegna, l’isola è interessata da profonde trasformazioni della struttura economica agropastorale tradizionale e, conseguentemente, del sistema socioculturale ad essa correlato. Le feste novenarie (istituzioni festive della durata di nove giorni) più importanti della Sardegna erano sottoposte anch’esse ad importanti cambiamenti, colti lucidamente dall’antropologa in un lavoro descrittivo e allo stesso tempo interpretativo che si declina come uno dei più significativi contributi dell’Antropologia culturale italiana. A distanza di quarant’anni dalla prima edizione de Il consumo del sacro, le “feste lunghe di Sardegn…

Fractional Maximal Functions in Metric Measure Spaces

2013

Abstract We study the mapping properties of fractional maximal operators in Sobolev and Campanato spaces in metric measure spaces. We show that, under certain restrictions on the underlying metric measure space, fractional maximal operators improve the Sobolev regularity of functions and map functions in Campanato spaces to Hölder continuous functions. We also give an example of a space where fractional maximal function of a Lipschitz function fails to be continuous.

On Descriptive Characterizations of an Integral Recovering a Function from Its $$L^r$$-Derivative

2022

The notion of Lr-variational measure generated by a function F ∈ Lr[a, b] is introduced and, in terms of absolute continuity of this measure, a descriptive characterization of the HKr -integral recovering a function from its Lr-derivative is given. It is shown that the class of functions generating absolutely continuous Lr-variational measure coincides with the class of ACGr -functions which was introduced earlier, and that both classes coincide with the class of the indefinite HKr-integrals under the assumption of Lr-differentiability almost everywhere of the functions consisting these classes

Bayesian estimation of partial population continuity using ancient DNA and spatially explicit simulations.

2017

Abstract The retrieval of ancient DNA from osteological material provides direct evidence of human genetic diversity in the past. Ancient DNA samples are often used to investigate whether there was population continuity in the settlement history of an area. Methods based on the serial coalescent algorithm have been developed to test whether the population continuity hypothesis can be statistically rejected by analysing DNA samples from the same region but of different ages. Rejection of this hypothesis is indicative of a large genetic shift, possibly due to immigration occurring between two sampling times. However, this approach is only able to reject a model of full continuity model (a tot…

Structural variables drive the distribution of the sensitive lichen Lobaria pulmonaria in Mediterranean old-growth forests

2015

a b s t r a c t We tested the hypothesis that structural variables related to old-growth features affect the distribution of Lobaria pulmonaria in a Mediterranean National Park of Italy. A total of 36 plots, with old-growth characteristics and representing overall three forest types (beech- oak- and mixed- forests) were studied. The lichen was absent in about half of the sites, suggesting that the selection of old-growth forests based solely on structural features is not sufficient to predict the presence of this species, which therefore proves to be rather sensitive and selective. Its abundance was related to high tree circumference and basal area, and to availability of deadwood, confirmi…
